Robinhood vs. Kalshi for Prediction Markets: Which Should You Use in 2026?
Robinhood and Kalshi share the same exchange infrastructure but serve different traders. A complete 2026 comparison of fees, markets, state availability, and the Rothera exchange coming in Q2 2026.
Robinhood and Kalshi have one of the stranger relationships in finance right now: they're partners, competitors, and running on the same underlying exchange — all at the same time. If you've landed here trying to figure out which one to use for prediction market trading, you've found the right place.
The honest answer isn't "Kalshi is better" or "Robinhood is better." It depends on what kind of trader you are, what you already use, and whether you care more about market depth, UI simplicity, or having all your financial assets in one app. This guide breaks down every meaningful difference.
How Robinhood and Kalshi Actually Work Together
Before comparing them, it helps to understand the plumbing.
Kalshi is a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO) — licensed and regulated by the CFTC. That means Kalshi owns and operates the actual exchange where event contracts are listed, matched, and cleared. When you trade on Kalshi directly, you're using the exchange itself.
Robinhood is a Futures Commission Merchant (FCM) — a broker that routes orders to exchanges it doesn't own. When you trade event contracts on Robinhood, your trades are sent to Kalshi's exchange (and also ForecastEx, the Interactive Brokers-affiliated exchange). Robinhood is the front end; Kalshi is the back end.
This means when you use Robinhood for prediction markets, you're still trading on Kalshi's order books. The same markets, the same prices, the same liquidity — with Robinhood's interface layered on top.
That's changing soon. In January 2026, Robinhood completed its acquisition of MIAXdx (formerly LedgerX) through a joint venture with Susquehanna International Group, renaming it Rothera. According to Robinhood's Q4 2026 earnings call, Rothera is targeting a mid-2026 launch as Robinhood's own CFTC-licensed exchange and clearinghouse. When that happens, Robinhood will operate more like Kalshi — running its own infrastructure end to end.
For now, though, the two platforms are structurally different in ways that matter for your trading.
Fees: Kalshi's Variable Model vs. Robinhood's Flat Rate
This is often the first question, so let's get the numbers right.
Kalshi's fee structure uses a formula: 0.07 × P × (1 - P), where P is the contract price. The fee maxes out at 1.75¢ per contract (at a 50¢ price). You're only charged on entry — selling a position is free.
What that means in practice:
- A contract priced at 50¢ (highest uncertainty): 1.75¢/contract
- A contract priced at 80¢ (high confidence): 1.12¢/contract
- A contract priced at 90¢ (very likely): 0.63¢/contract
Politics and policy markets on Kalshi are completely free — zero taker fees, zero maker fees.
Robinhood's fee structure is simpler: $0.02 per contract flat, every time. That's $0.01 to Robinhood as the FCM and $0.01 to Kalshi's exchange.
For most retail traders, the difference is small. But for high-frequency or high-volume traders, Kalshi wins on contracts priced away from 50¢, and Robinhood costs slightly more at that price point due to its commission layer.
Bottom line: If you're trading politics markets specifically, Kalshi is free. If you prefer predictability over optimization, Robinhood's flat $0.02 is easier to model.
Market Selection: Kalshi Has More; Robinhood Has Curation
Kalshi lists thousands of active markets across politics, economics, sports, crypto, climate, culture, health, and science. If you want to trade on Fed rate decisions, measles case counts, Grammy winners, or whether a supervolcano erupts before 2050 — Kalshi has you covered with a wide selection.
Robinhood currently offers 1,600+ active markets, focused on the headline events most users care about: major sports leagues (NFL, NBA, MLB, March Madness), elections, key economic indicators, and select culture contracts. The curation makes the experience cleaner for casual users, but dedicated prediction market traders will notice the narrower catalog.
This gap will likely shrink as Rothera comes online. Robinhood CEO Vlad Tenev noted on the Q4 earnings call that Robinhood intends to "list markets around company KPIs and fundamentals" as regulatory clarity improves, and that custom combos (bundling up to 10 contracts into a single multi-leg position) are already live and unique to Robinhood.
Bottom line: Kalshi wins on breadth. Robinhood wins on simplicity and the unique Combos feature.
Platform & Interface: Purpose-Built vs. All-in-One
Kalshi's web platform and mobile app were designed from scratch around prediction markets. You get:
- Full order book depth
- Real-time contract volume and open interest
- Detailed market rules and resolution criteria
- Price charts and historical data
- API access for programmatic trading
Robinhood's prediction market interface is integrated into its existing brokerage app. You get:
- Clean, mobile-first UI that stock and crypto traders already know
- Contextual market suggestions linked to equities (e.g., Tesla delivery contracts surfaced on the Tesla stock page)
- Combo feature for multi-leg positions
- No dedicated web trading terminal for event contracts
- No public API for prediction markets
If you're an active trader who wants to watch order flow and size into positions carefully, Kalshi's tools are more appropriate. If you already use Robinhood for stocks or crypto and want to add prediction market exposure without opening another account, the convenience factor is real.
Bottom line: Kalshi is the purpose-built exchange. Robinhood is the convenient gateway.
Regulatory Status and State Availability
Both platforms are federally regulated, but the legal landscape is complicated.
Kalshi holds a CFTC Designated Contract Market license — the same regulatory category as the CME Group and other major U.S. commodity exchanges. This means federal law (the Commodity Exchange Act) governs its products, and Kalshi argues this preempts state gambling laws.
That argument is being tested in court across more than 20 active lawsuits. As of April 2026:
- Nevada: TRO granted March 20, 2026 — sports, election, and entertainment contracts blocked; PI hearing April 3
- Arizona: First-ever criminal charges filed (20 misdemeanors, March 17, 2026) — sports contracts blocked
- Ohio: Federal court denied Kalshi injunction (March 9, 2026); sports contracts subject to Ohio gaming law
- Washington: AG civil suit filed March 27, 2026; Kalshi suing in federal court
- Tennessee: Kalshi won preliminary injunction (Feb 19, 2026); sports contracts continue
- Plus AG lawsuits in NJ, MD, MA, MI, CT, NY, UT (platforms operational in most while litigation proceeds)
Robinhood operates as an FCM and faces similar state-level challenges because it routes through the same exchanges. On March 30, 2026, Robinhood filed a preemptive federal lawsuit against Washington's attorney general and gambling commission, arguing federal law preempts state enforcement. GeekWire confirmed Robinhood intends to launch on Rothera as a third exchange later this year.
Robinhood's general availability: available in 49 states (Maryland excluded entirely from all event contracts); sports contracts additionally restricted in NV and NJ.
Kalshi's general availability: most states, with sports-specific restrictions in AZ, IL, MT, OH, NV, and NJ; and active litigation in 14+ states.
Bottom line: Both platforms face the same legal headwinds because they share infrastructure. Neither has a clean-state advantage right now.
Volume and Liquidity
Robinhood's 23+ million customer base gives it extraordinary reach. The platform traded 12 billion event contracts in 2025 — its first full year — and 4 billion more in just January–February 2026, per the Q4 earnings call. Annualized prediction markets revenue hit a $300M+ run rate in Q4 2025, and Robinhood said Kalshi hit $1 billion in daily trading volume on Super Bowl Sunday, partially driven by Robinhood's order flow.
Since Robinhood routes to Kalshi's exchange, Robinhood users are trading in the same liquidity pool as direct Kalshi users. The liquidity advantage runs both ways — Robinhood users benefit from Kalshi's market depth, and Kalshi benefits from Robinhood's volume.
The Rothera Factor: What Changes in Q2 2026?
This is the biggest structural question of the year. When Rothera launches as Robinhood's own DCM, several things shift:
- Robinhood controls the full unit economics — instead of splitting the $0.02 fee, Robinhood captures both halves (or restructures pricing entirely)
- Robinhood can list contracts Kalshi doesn't — proprietary markets, micro-event contracts, potentially company KPI markets
- The Kalshi partnership evolves — Robinhood has said it will "optimize for customers" by routing to whichever exchange offers best pricing, which may reduce Kalshi's volume from Robinhood
For traders, the practical impact is uncertain until Rothera is live. Robinhood has said it will remain open to other FCMs trading on Rothera, positioning it as a competitor to Kalshi for exchange business — not just a retail platform.
Who Should Use Which Platform?
Use Kalshi directly if you:
- Want the broadest market selection, including niche categories
- Trade frequently and want to optimize for lower fees (especially on out-of-the-money contracts)
- Need API access for algorithmic or programmatic trading
- Want full order book visibility before sizing into large positions
- Care specifically about politics markets (which are fee-free on Kalshi)
Use Robinhood if you:
- Already have a Robinhood account and don't want another login
- Primarily trade sports or headline political events
- Want to combine prediction market exposure with stocks, ETFs, and crypto in one view
- Like the Combos feature for multi-leg positions
- Are new to prediction markets and want a familiar, mobile-first interface
The "both" argument is real. Because Robinhood routes to Kalshi's exchange, prices for the same contracts are often identical or very close. Some traders keep both accounts open for the rare arbitrage window or to access markets one platform doesn't list.

FAQ
Are Robinhood and Kalshi the same?
No. They're partners, not the same company. Kalshi is the exchange; Robinhood is a broker that routes trades to Kalshi's exchange. You're trading the same markets when you use Robinhood's prediction market hub, but through a different interface and with an additional commission layer.
Do Robinhood and Kalshi have the same odds?
For markets available on both platforms, prices are typically identical or very close because Robinhood routes orders directly into Kalshi's order books. Minor discrepancies can occur during fast-moving events, which is why some traders monitor both.
Is my money safer on one platform vs. the other?
Both operate under CFTC oversight. Kalshi holds a DCM and DCO license; funds are segregated per CFTC requirements. Robinhood's prediction market activity flows through Robinhood Derivatives LLC, its CFTC-registered FCM subsidiary. Neither offers FDIC insurance on prediction market funds.
Will Rothera affect current Kalshi trades?
No. Rothera is Robinhood's new exchange, expected to launch in mid-2026. Your existing positions and account balances on either platform are unaffected by Robinhood's exchange infrastructure plans.
Which platform is better for sports prediction markets?
Both platforms currently face state-level restrictions on sports event contracts. As of April 2026, Maryland residents cannot access Robinhood prediction markets at all. Sports contracts are additionally restricted in Nevada and New Jersey on Robinhood. Kalshi has sports-specific restrictions in AZ, IL, MT, OH, and NV/NJ, with active litigation in 14+ states. Check current availability in your state before trading.
Conclusion
Kalshi and Robinhood aren't really rivals in the traditional sense — they share the same exchange infrastructure, and Robinhood's massive user base actually makes Kalshi's markets more liquid. The real competition is in the interface, the fee model, and the question of who owns the customer relationship.
If you're serious about prediction markets, Kalshi's purpose-built platform, broader market catalog, and free politics trading are hard to beat. If you're primarily a Robinhood user who wants to add event contract exposure without adding another account to manage, Robinhood's integration is seamless and the fee difference is small for most retail volumes.
The most interesting chapter starts when Rothera launches. At that point, Robinhood stops being just a distribution channel and becomes a full competitor to Kalshi for exchange business. For traders, that likely means more competition, better pricing, and a more interesting set of markets.
For now, both platforms serve the same underlying market. The question is just which front door you prefer.
